plot_conn_comps {CKMRpop}

plot the graph showing the connected components

Description

This is a simple wrapper for some tidygraph/ggraph functions that will let you find the connected components of a graph in which the related pairs are connected by edges. It also makes a plot of them.

Usage

plot_conn_comps(Pairs)

Arguments

Pairs

the tibble that comes out of compile_related_pairs(). For this function it must have, at least the columns id_1, id_2, and dom_relat.

Details

Note that it appears that the 'ggraph' package must be loaded for the plot output of this function to print correctly.

Value

This returns a list with two components:

• conn_comps: a tibble with three columns:

  • name: the name of the sample

  • cluster: the index of the connected component the sample belongs to

  • cluster_size: the number of samples belonging to that cluster

• plot: a ggraph/ggplot plot object showing the connected components as vertices with edges between them.

Examples

# get a Pairs tibble from the stored data
Pairs <- compile_related_pairs(species_1_slurped_results_1gen$samples)
PCC <-  plot_conn_comps(Pairs)

# look at the conn_comps:
head(PCC$conn_comps)

# if you want to print the plot, that seems to require
# loading the ggraph library
library(ggraph)
PCC$plot
